To avoid the deterioration of the waterproof and dust proof performance
Check the following and use the unit correctly.
-
Be careful not to drop the unit or subject it to mechanical shock.
Deformation or damage may cause deterioration of the waterproof and dust proof performance.
-
This unit does not have a design that is resistant to water pressure. Use of the unit in a location where high water pressure is applied, such as in the shower, may cause a malfunction.
-
Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on the unit directly. Also, never use the unit in high temperature locations such as in saunas or near a stove.
-
Handle the cap with care. The cap plays a very important role in maintenance of the waterproof and dust proof performance. When using the unit, make sure that the cap is closed completely. Be sure to close the cap with the
mark facing up so that foreign objects do not enter inside. If the cap is not closed completely the waterproof and dust proof performance may deteriorate and may cause a malfunction of the unit as a result of water or dust particles entering the unit.
